Why one server is better
Most SaaS products don't need microservices, Kubernetes, or multi-region deployments. A single Hetzner server with 8-32 GB RAM can comfortably handle thousands of users.
With Stacknaut, your frontend, backend, and database all run on one box. Deploy with a single command. No load balancer fees. No inter-service networking charges. No surprise bills.
Even better — you can run multiple apps on the same server. Testing three SaaS ideas? That's one $27/month server, not three separate $50+/month hosting bills. For indie developers searching for product-market fit, this alone can save hundreds per month.
When you actually need to scale, you can. But most indie SaaS products never reach that point — and the ones that do are profitable enough to afford it.
Own the boring infrastructure
Turn the hosting savings into a working SaaS foundation.
The calculator shows the monthly cost. Stacknaut gives you the code and infrastructure to actually run that setup.
What you get in Stacknaut
- One-server architecture for frontend, backend, API, Postgres, and logs
- Terraform and Kamal config you can adapt instead of inventing
- Async Guided Launch support for the first deploy on the $799 tier
These are ballpark estimates to give you a rough comparison. Every provider prices things differently — per-seat, per-service, usage-based, with free tiers, credits, and overages that make exact comparisons difficult. Hetzner costs assume a single dedicated-vCPU server (CCX series, EU region) running all services. Vercel costs include external backend hosting since it can't run persistent servers.
